At ACO Building Drainage we recognise the importance of implementing the right drainage system. All too often however, drainage is overlooked and carried out as an afterthought.
With increased flooding across the UK and the new guidelines on Sustainable Drainage Systems (SUDS) it is essential that designers and construction specifiers of building projects take the time to implement an effective drainage system that will prove durable and cost-effective long-term.
Peter Jennings, Technical Director for ACO Building Drainage takes at look at the things to consider when designing a drainage system for your project.
1. Flow capacity
Areas with impermeable surfaces need a drainage system designed to efficiently convey surface water. The capacity of the drainage system must be able to carry the expected flow at any point in the system to prevent unwanted surcharge or flooding.
The specification of the drainage system must consider the rainfall intensity, storm duration and the return period of flood and storm events to the area of the building. An appropriate solution will balance the risk and consequences of flooding against the cost of the drainage system.
Designers must choose a material that provides the required hydraulic capacity and maximum durability. Modern manufacturing techniques, including CNC manufacturing processes, mean it has never been easier to deliver a cost-effective solution that meets the both the practical and aesthetic applications of the project.
3. Modular vs bespoke drainage systems
While bespoke drainage offers a tailored solution, off-the-shelf, modular design drainage systems can offer significant advantages during installation. Modular drainage systems can be adapted to meet most situations and can be sourced quickly, reducing costs and saving time.
4. Load bearing capacity
Drainage systems in precinct areas may have different load bearing requirements than off-highway applications such as car parks. Industry recognised load classification provides guidance on which gratings and covers are suitable for specific applications. It is also important to consider emergency vehicle access requirements, particularly when designing drainage for a pedestrianised area.
5. Performance and security
The latest generation of high performance drainage systems offer enhanced water flow capability through grating geometry. They also feature security fixings that prevent vandalism and theft. These systems are often overlooked in favour of more conventional units, despite the improved long-term performance they offer. Designers should consider all possible options when choosing a drainage system.
With increased flooding, as well as, conversely, a greater need for water conservation, drainage systems have to work harder than ever before. Luckily there are also more options, guidelines and support available to designers and specifiers.
